Yeah, I know the feeling. Been to 170-175 myself and I still have no clue as to when it ends.
It is really amazing. Why on earth would someone buy an RX-8, a G37, or a 370z when this little diamond is around for about the same price. Heck, it even weighs far less than the M3, and can be made much faster with just a few basic mods. It is only a few hundred lbs heavier than an RX-8, it weighs like 500lbs less than the G37 or the 370z. Yet you have FAR more hp potential out of the box than they do.
I am not a big fan with how the new BMWs look, but I love what you have done with yours being ultra clean and nonricey. And I love its concept. Less weight, big inline, and with a turbo.
Great find!
Honestly, this really should just be an M1
I can give a few honest reasons why one would choose one of the other cars over the 1.
The 370z and the RX-8 are better handling cars out of the box. While the actual #'s are pretty close, the 135i feels a bit soft at the track. It also doesn't have a mechanical LSD, while the others do. It has an electronic LSD which works fairly well, but not as well as a real LSD. BTW, I'm pretty sure the 370z is at least 100-200 lbs lighter than the 1. Those are great cars out of the box. If I had no plans to mod my car, I'd probably be in one of those instead.
Then there's the pice factor of BMW's. Base price is cheap, but you really get nothing. The MSRP on my 1 was close to 50k. So if you are looking for a well-equipped car, the japanese cars look like a bargain. I think the main reason there aren't very many 135i's on the road is because once you start equipping them with options, the 3 series is around the same price. And unless you are a true enthusiast, most see the 3 as a better car because 3 > 1.
Truth be told, a base 5 series would have been cheaper than my car. But there's also the fact that the 335i coupe is a beautiful car. I can understand people seeing the 135i as ugly. Personally I love the look. It has an aggressive bulldog stance while the 335i coupe is sleek and sexy.
And finally there's reliability. I can easily say that if long term reliability is a big concern, definitely stay away from BMW.
Especially with these turbo engines. I've had more problems with the 2 bimmers I've owned in about 1 year than I have had with all my japanese cars of the past 16 years. BMW's are well-engineered, the attention to details is impeccable, but they tend to have a lot of little issues here and there. For example, all of the bimmers that share this motor right now (135i, 335i, 535i, Z4 s-drive) are having fuel pump failure issues. It's been an issue for a few years and BMW still hasn't figured out what the problem is. They increased the warranty on this part to 100k miles, but you can be stranded at any moment.
However, negatives aside... The car is a blast to drive. So enjoyable, in fact, that I would gladly buy another BMW even with all the issues. (Then again, I say that now, but who really knows 4-5 years from now.) And yes, the main reason I grabbed the 135i over anything else in it's price class is because of its potential. That and there aren't very many of them on the road. I think I see more current generation M3's than 135i's.
