the car has 139000 miles how many miles do you think i could get out of this engine. my friend said ill have to replace it real soon.
As soon as i saw your post i just had to sign up an account to reply to it
I have a BMW E30 318i and it was made in 1989, most of the people would consider it a lesser BMW due to it's 1.8L M40 engine, and mine has the silly cloth seats that have seemed to have pretty much fallen apart from age and ware, when i got it i serviced it and it needed about $700 of work done to get it ready for a roadworthy. and have since had to replace the clutch slave cylinder which cost me $45 and $80 to have someone install as i don't have the or resources to fix it my self keep in mind i am in australia so my prices will be in australian
When i got the car the oil was quit dirty so i did a full service replaced plugs and all filters, and even drained the gearbox and differential and replaced all fluids i.e. power steering, and water + coolant + oil.
I also had to modify a set of leads for it as it seems to have some kind of ring on the 4th lead? so i purchased a set of NGK leads for aprox $60 cant remember the exact price because it was a while ago, while the original BMW ones were $300. Anyways i un-crimped the 4th lead on the new set and cut the little black round thing off the old lead and slipped it back together and and re-crimped it, and its run like a dream ever since.I have also had a pull a few panels out of the dash and push in a few light bulbs because they had come loose and didn't have some dash lights at night, and the electric ariel doesn't go up and down and will cost me $140 to replace or $75 for a new areal mast, i have just discovered that my rear breaks are shot which is partly my fault for not double checking when the mechanic said that they were fine and partly because I'm not very good at keeping the linings on my breaks lol
But all of this had to be done due to its age and milage and my paranoia as the car was purchased for $800 from our local car dealership, it has done the last time i was looking at it 310,000Ks ( 192,625.1 Miles ) it was sitting under a tree covered in leaves looking sad and lonely lol. it wasn't sold with registration so i had to redo all that so i guess the total purchase cost was around $2500 all up. And i love it .. it drives perfectly and compared to our other car it's not even in the same league, and it was made in 2000!
Even with it's shot suspension it doesn't wander on the road or play up at all and drives perfectly straight. and if i want to it would take corners sideways overtake big trucks at warp speed and get me charged by the police who are currently enforcing hoon laws

and that is with out any modifications to the engine internally.
it is truly an experience to drive and to be honest it's never let me down even when the clutch slave cylinder buggered up, i was about an hour away from home and i borrowed some break fluid, filled it up drove home and it crunched once when i got to my driveway.
So would i recommend one ? absolutely are they expensive to maintain ? not if you find the right places to get your bits from. dealers = expensive

and don't seem to be that bad on fuel. I haven't found that many cars that i cant keep up with it in so as far as being gutless. I don't have any issue with it, i mean I'm not going to take it to a track anytime soon but it's just to drive around and get me to work and stuff it's 100% fine for that.
I"m looking to put some nice wheels on it at some point and fix the suspension and maybe if i get rich, fix the paint up a bit, And maybe lower it, and that's it leave the rest stock and i cant foresee it blowing up any time soon, A mechanic at one of the bmw places i get my bits from said if i looked after it i would get as many miles again out of it. As long as you maintain it know a bit about the pit falls of buying second had cars i don't think it would matter what model BMW you end up with, it's probably going to be a good car, keep in mind that the older the model the harder parts become and more costly stick with the popular models and you wont have an issue with any of them.
Peace.
