Poll: MRC 500 S4 or remapped/Milltek/FMIC B5 RS4?

[MilkybarKid]

Once i get my s4 "MRC'd" i wont be selling it! petrol prices/labour costs wont bother me.
Ive not bought and sold many cars, mainly just bought them, for a real example 1.5k on the bug, 3k on welding/electrics, 6k+ on its engine, 2k on the box, 1k on its suspension, 500 on the brakes, 200 on the SHIFTER! + all the rest, ill only end up with a car i could sell for maybe 4k. if im lucky. Its scary how much there is to lose but thats just one of the things you have to expect.
If i had enough cash to buy either or id go for the rs4, but i dont so ive got the s4 for £6800 and now im having to spend around the same if not more on the upgrades. If i was to sell it i know i wouldnt get much mure (if any more) than i paid for it.
