I was talking to him before I bought my car, and he said the car is only on DD cause he wife is making him sell it, so if that's anything to go by, he won't fluctuate on price at all anyway...
And, take this with a pinch of salt if you like lol
But, 21k for a non widetrack, UK STI with 130k miles, is too much. Its up as kms, but its miles.
He did say it was in flawless condition, but I didn't go for a viewing so can't say if it's true.
