You've missed a spot
Volvo 142 (of any year)
Oh, and I also made a wordle (wordle.net) of the 15 000 most common words in your list. Just in case someone can't be bothered to read through the entire list they can get a quick overview of the contents.
And it also reveals that the most common years in the list are 2007 and 2006. They're probably the most google-friendly years (most information available on the internet for those years, as older years aren't contemporary and newer years hasn't had the time to accumulate as much information yet) I suppose, so that might explain why they are the biggest.
Edit: Is the Holden HRT V8 really a car? The only info I've found is that it's a toy car modeled after an Holden Commodore used by HRT in the V8 series. It seems like Holden HRT V8 is a bit like saying "Chevrolet Nascar", it's not a model, just a description of a type of car.
The Jaguar XJ220 LM Race Car does not exist in real life, only in Gran Turismo. The real life racing version is called JX220C.
The Lotus Toyota Venza is a design study (at least, all pictures I've found are sketches and 3D renderings), not a car or concept car that has actually been built.
Mazdaspeed MX-5 A-Spec, B-Spec and C-Spec seems to have been Gran Turismo 2-creations and not real cars. The only info on Mazdaspeed MX-5 LM Concept is from a fake GT5 car list published back in 2007.
The Meyers Manx Kubelwagen replica was actually completed by David Deal (if
this is correct). It seems like Meyers Manx abandoned the car when the Volkswagen Thing was released (in 1968), so that puts a timestamp on when the replica project would have been started at least.
The only mention of a Mini Cooper Quick 3.0i that I can find is from that fake GT5 car list from 2007 mentioned above.
Mitsubishi CZ3 Tarmac Rally car does not exist. The CZ3 Tarmac is a concept car, the rally car is PD's interpretation of it as a rally car.
Mitsubishi FTO Super Touring Car does not exist in real life, only in Gran Turismo.
The Oettinger Corrado 5V Turbo is probably a 20V Turbo (5V per cylinder). The year is then "around 1992" according to the internet.
Reliant "Anabol" is actually Anadol.
Scion Exile only exists on paper. It's a design concept.
Seagrave Firetruck is not a model name, it's a description (like Boeing airplane). Also, it's not a car, it's a firetruck.
Toyota Altezza LM Race car is a PD creation, not a real car.
