After getting a little frustrated with other sites, I went ahead and took a stab at my own. It has a simple, clean interface with quick sorting and filtering, along with photos of nearly all of the cars. It's a work in progress, but it's shaping up nicely.

Thanks to Famine, TornadoAlley, and baxnimis for their hard work compiling the various data and sharing them with others.

You're missing PP, which is quite important. Apart from that, your interface is much nicer than mygranturismo.net. You gonna add the facility for us to save searches?

EDIT: Drivetrain would be nicer as a multiselect: if I'm looking for rear-wheel drive I'm not that fussy about FR, MR or RR, so long as it's *R

Yeah, I just took Famine's master list (thanks Famine!) and put it online, he didn't track PP, so I don't currently have it. If I can find another database that includes them, I'd consider adding them to site. Or... maybe it's time someone figured out the equation used to calculate them... Hmm...

For the most part, this is already there. After performing a search, the current URL should be all you need, you can bookmark it and come back to it. Would you prefer a button or link that copies the current search URL to your clipboard?

This will be coming via an "advanced search" option. The backend already supports it. The search you're looking for is http://gt5cars.heroku.com/cars?sear...n_eq_any][]=RR&search[drivetrain_eq_any][]=MR

Thanks for the feedback!

No, you're quite right - I've never bothered with PP (and it's changed from version to version quite often :lol: ), though I can't really put my finger on why I've chosen not to.

I've got a weekend of ploughing through the remainder of my car list for accurate stats (found 3 more weight anomalies this week :rolleyes: ), so you might be looking at a completed list on my behalf by next week. I'll e-mail you a copy.

The volatility isn't one of it's better features, and a quick search shows that it's utility is in question... I'd like it better if I understood how it were calculated. Perhaps I'll take a stab at a regression over the weekend.

I very much appreciate your tenacity and attention to detail. I'd welcome the chance to keep my site's database up to date with yours.

I hadn't noticed the URL contains the search, that's nice. I asked because your stored searches box at the bottom implied it was coming :) Bookmarks are fine for me.

Problem with getting PP is actually finding the number. For premium you can just go through the garages noting them down, but for standards you have to wait for the car to appear in the UCD, and even then it's PP will vary depending on milage / how screwed the body/engine/oil is. Most standard value is probably-> buy from ucd, change engine, restore rigidity, note number, but that's a lot of work.

The beta on the box at the bottom is because I don't have all the events listed yet, and haven't decided how I'm going to handle some of them. The K Cup and Truck events require a raw list of the cars eligible, which makes them a little more "manual" to implement.

Yeah, the UCD kinda throws everything for a loop that way, which is why I like the idea of trying to reverse engineer the equation used to calculate it. Still, getting enough data to do even that might be a lot of work.

👍

I've been meaning to gather some PP data and run it through SPSS but I've been too lazy to actually do it so far. Maybe I'll give it a shot too and see if we get the same numbers.
 
nice website but it doesn't work on the PSP's web browser :indiff:
I apologize for that. I don't have a PSP with which to test it sadly. Can you elaborate a bit more about what you mean by "doesn't work?" The site does use javascript, but is designed to degrade nicely in the absence of javascript support.

Thanks for the feedback,

One silly question, what's the letters in "Avail" column stand for?

I'm guessing U-used, N-new, W-win?, T-?
Your guesses are all correct.

D = Downloadable Contnet (aka DLC)
N = New
T = Ticket*
U = Used
W = Won

*When you complete certain race series, you're given a "Random car of level X" ticket. That's what the T indicates. The prize list thread can show you which events reward you with tickets of which levels.

If you're using a browser with a cursor (ie, a normal PC or Mac), there's a mouseover on the availability column's header that describes the codes. Or, if you click on a car's model, each car's details page lists its availability in words, rather than the space-saving letters used in the index table.

Sure I get a message saying

"We're sorry, but something went wrong"

"We've been notified about this issue and we'll take a look at it shortly"

Ironically, the notification of which they speak isn't installed by default, and due to the free nature of my web host, my logs don't go back far enough to see the error you encountered. Once I get the error notification services setup, would it be OK if I PM'd you and asked you to visit the site again with your PSP so that I can see what the trouble is?

Thanks, and sorry again for the trouble.

I've just added the ability to search TornadoAlley's used car dealership database online. Enter the top eight cars in your current Used Car Dealership, and see what's coming in the next five game days, or when a specific car will be in your Used Car Dealership.

The UCD search is still a little rough around the edges, play around with it and let me know what you like or don't like!

Just a pointer. Premium says True or False instead of Yes or No.

Good site though. Keep it going, you never no it may just take off.
 
I've added a rarity column to the used car dealership table. Each car's rarity is rated on a 1-5 scale with 5 being the rarest, and 1 being the most common. The rarities are specific to each of TornadoAlley's master lists. This means that a car with a 5 rarity for a person matching Master List 1 might only be a 4 rarity for someone matching Master List 2. If eventually the two master lists are merged, then the rarities would become the same for everyone.

With this feature, people can make better decisions about whether to buy car X now, or wait for it to come around again later. Since I also have the "when will I next see car X" feature, you can (hopefully) determine just how many game days have to go by before you'll see the car again.

Warning, below this point lies math!

Car X in Master List 1's rarity would be calculated like so:

occurrences = number of times Car X appears in Master List 1
most_rare = minimum number of times any car appears in Master List 1
least_rare = maximum number of times any car appears in Master List 1
raw_rarity = 1 - [(occurrences - most_rare) / (least_rare - most_rare)]

At this point, each car's raw_rarity is a value in [0, 1], with 1 being the rarest, and 0 being the most common. To convert to the 1-5 scale I do the following:

sigma = standard deviation of raw_rarities for all cars in Master List 1
mu = average of raw_rarities for all cars in Master List 1

if raw_rarity > mu + 2 * sigma, then rarity 5
if raw_rarity is [mu + sigma, mu + 2 * sigma), then rarity 4
if raw_rarity is [mu - sigma, mu + sigma), then rarity 3
if raw_rarity is [mu - 2 * sigma, mu - sigma) then rarity 2
if raw_rarity is [0, mu - 2 * sigma) then rarity 1
