I kept the last two 325iS until they had more than 100,000 miles on them. I am a little afraid of what a 135i engine is going to look like with that many miles on it. The 128i engine is just an advanced version of what is in my 325iS so it should last a long time.
The 135i and my M-Sport 128i have the same top speed, 155 MPH. I will admit that the 135i will get there quicker, but I really don't think that I need that. The 128i is plenty quick and plenty fast.
