We can imagine that tuners have been anxious to start hawking their gear for the 2008 BMW 1-Series as the car has a lot of potential and lacks an "M" version. HARTGE, which also tunes the hatch version, has their first round of offerings available and they include the expected wheel/tire combinations, an adjustable sport …

For around $160,000, German tuning shop Hartge will deliver a BMW 3-Series that's been fitted with a moderately juiced V10 from the M5. The resultant 550-hp H50 isn't exactly a moderate runner.
