Keep your nice 4200s and save your £10k...its not worth the swap.
Yep... older and wiser.
You can get the same ride quality by removing the tyres off your 4200.
Given the choice I would rather have my 2006 MY 4200, with its GS front splitter and x pipe over the same year GS I have now even without the extra £10k. But you can't turn back time.
Comedy auctions.... If it were me I'd just drop the price like I did with the 3200. Maybe that's why I'm not a car dealer....
.........and its back again .
