    • There's a lot of high mileage 335's out there with minor mods who cope with a few track days a month and then behave nicely as a daily. I don't want to keep throwing money at this car, I'm not in it for much yet  and once I get the LSD there's really nothing else I need to do besides keep up to date with maintenance. Everything that breaks easily has been handled (minus HP Fuel Pump) which should give me a lot of trouble free motoring in future. It's definitely inside BMWs' "horror period" I get that, but I do think you're being a little overly harsh. I'd like to hold on to this for only another few years at least and then consider a step up into an F80/1 M3/4 when I can afford a good'n. I also like B58's and would move into a M235i or similar when they're a bit cheaper.
    • I mean nah, lets be honest it's significantly worse. BMW's are absolutely not the same age, replacements are not the same level of robustness. Most would say an E36 is more solid than an E90X and I would still say an E36 is a little more rickety than your equivalent R chassis over time. BMW pretty much have a huge void between E36 and anything with a B58/ZF onward. I kinda get the appeal if they work, but they just don't. I get that the vibe is "do a track day in executive comfort" but in all seriousness, a VE Commodore is as comfortable and certainly more solid* around a track, and they are hardly up there in the high list of "Excellent track cars". See also: Barra Turbo with coilovers or _something_. I mean a great deal of these cars/choices are always irrational, but I at least try to stay rational, or at least have some rational argument why I did X and not Y :D. My pet peeve is irrational badge snobbery. There is no reason to buy a Luxury SUV when anything from Kia will do the job better, and cheaper. I know someone who has a twin turbo diesel X5 making 400kw or whatever and as soon as he opens his mouth I say nothing but "You are an idiot who has wasted your money" and tell him to buy a Tesla Model X/Y as it is superior to anything he will do with that car. (he does not like this, but he deserves it, just trust me..) But Prank seems like a nice guy. I want him to sell this 335i before sadness kicks in more and buy something far happier at the track, like an 86, or a Megane RS, or an Evo, or even save the money on mods and buy a 440i/240i/etc and bypass the painful years between 1997 and 2015 for BMW.
    • Haha most are for LHD though!  
    • Honestly, can't be worse than Skyline ownership which is also a mess considering the age of these things. The 335i at least you can still get parts easily.
    • Looks nice Shan. Every time you post its about a different car!
