You need to remember that the market doesn't work as simple as that mate, Some people buy cars like 25th anniversary Golfs to lock them up in storage in the knowledge that 10 years after it's been released it's still going to be worth shed loads!
This guy has got himself a standard cupra with low miles if he keeps it standard and does weekend mileage (say 2/3k per year I'd imagine in 3 years time whean 95% of cupras are chipped and modified with 80k on the clock and he has a standard cupra with 37k on the clock - it'll still be worth quite a bit.
This isn't going to apply to a 1.4
ibiza, and people with cupra R's seem to think that their cars are already worth a 2k+ premium over the cupra ... I am sure in 5/6 years time they will be extreamly rare standard and being a limited edition 10 year old car these will be worth a lot more than your average 10 year old
mk3 ibiza.
Make sense?
Like thermalp4 said about the VR6 ... yehh a VR6 is a good find with below 80k / standard and no rust but if you do find one they're not cheap! and the highline is worth more again
I still see 2001 106 GTi's with 20k on the clock going for well over the parkers
guide - but they are selling! ... hardly a classic on a 2001 plate but in 20 years time I am sure people will look back and say that the 106 GTi was a brilliant car as they do about the 205GTi and Mk1 Golf GTi's now.
