I'd tend to go for a Japanese model when buying an older car. Also, try and write off the cost over say 3 years (i.e. if you're borrowing, borrow for the length of time you think that you'll keep the car for), so when you come to sell/scrap you will not be making a 'loss'
I had a bit of trouble trying to get rid of a 99 Almera with 105k miles on the clock recently, but got a good enough price when I traded it in against another new car. I think it was the mileage rather than the year that put people off. Have to say that the car was in great nick though, and I had bought it with 92k miles on the clock.
