For an everyday car there are perfect..Ive owned mk5s and a mk6 before and all are great for everyday..I did use my old 225bhp jamsport tuned s2 for everyday use and it was prob the worst thing ive ever done..No powersteering shit fuel bills etc..Hence why it was fucked off to buy the mk5 rs below.

The rs2k will give ya 25mpg town use and alot higher on motorways..
Tuning wise if you know what your doing you can get about 175bhp like mine which cost me less than 400 notes

Id say go for it..Much faster than a 2.0L zetec
