If you're happy with it it's far from silly! I can possibly beat that anyway. I paid 6k for mine with 62k on the clock, replaced an air strut with a used one, replaced the whole lot with Arnott air struts, decided to replace the whole lot with conventional springs, replaced all the other suspension components even though I didn't need to, changed the wheels, new tyres (even though the others were perfect) replaced the radiator and one or two other things. Anyway, I'm more than happy with it now and it was my money. Whoever buys it next will get a bargain that's for sure!
