been offered a swap for my s1 for a Lreg m3 coupe in avus blue, looks ok condition wise dont think theres a lot of service history with it tho

says vanos akes a noise for 5 secs on startup but its normal on them?


never had a m3 before so am tempted but im thinking my s1 is worth a little more or more to the point an easier seller too

opinions?
