BMW 320i E46

小弟想出部04~05年320i E46操車,上28car睇完價錢大約$3xxxx~$5xxxx,有啲問題想請教各位師兄:
1. 點解差一年價錢會差咁遠?呢個年份嘅320i平均價大約係幾多?(撇除部份盤係車行)
2. 買呢個年份嘅320i有咩要注意?(好多人話高年份嘅歐洲車整多過揸,維修又貴!本身小弟買嚟都係做假日車,一個星期都係揸一~兩日,亦明白維修必定比同齡日本車貴)
3. 點解同齡嘅318i價錢同320i差唔多,有啲盤甚至乎318i重貴過320i!理論上BMW直六引擎會比直四引擎好,馬力/扭力都大啲,究竟咩原因會咁嘅呢?
4. 因為小弟係新手,冇相熟車房上架,請問搵HKMI驗車有冇問題?會唔會比搵車房上架冇咁好?

煩請各位師兄指教!

電子野多,最衰的唔係一炮過要整幾萬(係的話湯左佢算),而係一個月壞一個sensor有千幾兩千,隔個月就第二個sensor出事,夾夾埋埋一年就萬幾二萬

維修費咁緊要?咁驗車嗰時check唔check到邊啲sensor有問題/將近有問題架?

SENSORS都係呢D價錢架喇,驗車果陣主要睇有冇撞,篤電腦就睇倒佢有冇整熄左D ERROR CODE,有你就自己小心,但通常如果同車行買好少有呢樣野比你搵得出黎,睇下手數囉,同埋上手係咪渣唔夠一年就放…

1. Cousin - brand new 330i as family sedan - all factory no mod - non-stop problems - changed to Honda Stepwgn
2. Friend - brand new 320i as family sedan - all factory no mod - blown engine at traffic stop - junkyard

師兄,當年買新車都咁大鑊?但係依家重有好多BMW E46款喺條街行緊喎?

我有兩個同事都係揸BMW,一部03年320i,壞冷氣,上年換車時賤讓(好似執番10K),一部01年520i,前年壞波箱,擋了.執部十年過外BMW,take your own risk.
不過兩個同事都換返歐洲車,大家明白十年壽命,再多當賺.
反而我有個同事有部十幾年Corolla,貌似爛鐵,換車時賣左俾個地盤佬,執番十幾K.

E46 steptronic auto is the highest concern.  Either the GM or the ZF has a high probability of losing reverse.  The GM is a cheaper fix that needs a new solenoid, the ZF needs a new torque converter.  Both requires unmating the transmission from the driveline and engine.  The best solution to the problem : Get a manual.

The M54 engines are pretty solid, but they don't like slow city driving.  They will develop a carbon buildup issue down in the piston rings and make them bind.  They are engines that respond well to an Italian tune-up.  Baby the engine around all the time, it will blow up on you.  

My E60 has a M54B25 that's run 150k km now, I reach 6k RPM at least once per day, once everything has warmed up of course, and it's as smooth and responsive as an NA I6 should be.  

Some problematic areas for that era of Bimmers: (Assuming your engine and transmission is healthy)
-Water Pump (Engine Driven, composite impeller.  Impeller will shatter and not circulate coolant.  You have seconds to shutdown the engine or you will overheat the engine and warp your head)  Cost to fix: ~$600-800 new OEM pump, DIY or add labour
-Coolant expansion tank (plastic, gets brittle with heat, leaks all your precious coolant onto the group.  See above. )  Cost to fix: ~$500 for a tank, DIY this, and then replace your coolant hoses if not done yet.
-Valve cover gasket (Rubber gasket will plastcize with the heat cycles.  Hard gaskets don't seal very well and oil will leak into your spark plug well and onto the exhaust manifold.)  Cost to fix: ~$350 for new gaskets, DIY or add labour
-DISA valve (Controls intake runner length, plastic parts will wear out and fall off.  Unlucky ones will end up falling right into the intake valves and down into the cylinder.  Engine go boom.)  Cost to fix: depends.  If the DISA is still healthy, an aftermarket enhancement kit will correct the problem.  ~$800ish.  New DISA valve around ~$2k. Definitely DIY this one, it's 2 T40 bolts and 1 cable.
-VANOS rattle (The vanos solenoids seals will flatten over time and not seal properly.  The piston will rattle around its bore.  Car will feel lethargic below 3K rpm.)  Cost to fix: $250 for new seals made of better materials.  The problem is getting inside the VANOS unit to do the repairs.  Not a DIY for everyone, do it with the valve cover gasket cause you need to take it off anyways.
-Idler Pulleys (worn bearings) Cost to fix: ~$5-600ish for the 2, DIY them
-Window regulators (Windows stuck or rattling) Cost to fix: $800 parts, probably not a DIY for everyone so add labour
-Electricals and ECUs Cost to fix:depends
-Front control arm and Rear trailing arm (Worn rubber bushing, causing noise and alignment issues) Cost to Fix: About ~$800 each, and probably not DIY for most people

E46 may still have a mechanics engine fan that is driven off the crank pulley via a clutch, may need a fan clutch removal tool to do some of the DIYs.  Retrofit an electric fan while you're at it.     

The above is not a complete list, but most items are maintenance items that should be done on schedule.  If you want something that's reliable, get a new car.  If you don't mind working on your car and dealing with it's tantrums and moods once in a while, you can get something cheap and fun to drive.
