I did the opposite I went from a lightly modded E82 135i to a decently modded E46 M3. Stock for stock I regret buying the 135i and should have bought the E46 M3 in the first place but now I that I have my E46 M3 almost complete I really can't see myself wanting another car for quite sometime. Helps that the E46 M3 has been a dream car of mine for sometime. To make things clear I bought the 135i brand new from factory (dealer ordered) and the E46 M3 was mainly stock other than some less than ideal tires on stock wheels, legal tint, and G Power pedals. I have autocrossed both cars several times and prefer the M3 for both daily driving and track time. In the 135i's defense it was slightly better on gas, but it had a smaller fuel tank. The E46 M3 always surprised me with its range on many occasions.

Mods on my former 2009 BMW 135i: BMW Performance exhaust, BMW Performance carbon fiber diffuser, BMW Performance carbon fiber spoiler, BMW Performance electronic steering wheel (first version), BMW Performance selector lever and boot (Steptronic), BMW Performance rotors (front and rear), BMW Performance Power Kit, BMW gloss black kidney grills, APEX ARC-8 wheels, Dunlop Direzza Z1 Star Specs (225/255), Evolution Racewerks charge pipe with Synapse Engineering BOV, Sprint Booster, Vishnu Procede V4, and occasional helpings of 100 octane pump gas when I could afford it.

Things that broke with my 135i under warranty: 3rd brake light lense cracked and fell off multiple times, passenger side fender mounted turn indicator cracked and fell off held on only by wire, replacement of high pressure fuel pump, replacement of 3 faulty fuel injectors, and crappy iPod Y-connector wire. Car was owned for 2.5 years and had about 38XXX miles.
