My 2 cents... Importing with less than 15 years might be tricky.
On the Peugeot subject, I recently moved to Mexico for work and bought a 2008 Peugeot 207 RC (GTi), paid less than $10,000 CDN (MSRP $25,000), and it is an AWESOME car to drive.
A trick if you will import an ODD car, look up the design history, e.g. my 207 RC uses the same engine as a Mini Cooper S. Yes suspension part would still be.. not hard... just lenghtfull to get, but at least the engine parts easy, as they will be probably be required more often. (Just like the Ford Ranger shares parts with the Mazda B200 pickup, SEAT cars use Volkswagon parts)
The 406 Coupe above... you can get one for $5,000 - $6,000 CDN in Mexico (but all automatics).
Things I heard: dont even try to import a pre-2012 Ford Focus ST / RS from Mexico, they will deny it, and importing illegally will result in the car being crushed.
On the UPPER HAND, you can Temporally Import any car (some conditions apply) under a Temporary Permit for a limited period of time (I believe 6 months), then it must exit the country.
So I can go to Montreal with my 207 RC, by obtaining a temporary permit crossing U.S. border then Canadian border.
Research is a big MUST to import such cars.
All this said, John Scotty in Montreal imports rare cars from Europe such as Lotus Elise and others... so importing is do-able... maybe look up Import Brokers in the yellow pages.
