Your DAD is TOTALLY WRONG! ANY BMW is WORTH buying as they are SAFE and ALSO cause they are CHEAP to own! BUT>>> they MUST never use VALVOLINE or other CHEAP OILS! Only LONG LIFE -01 oil may be used! They have the BEST BALANCED brake systems and AUDI is basically their BROTHER or COUSIN! At 100k miles they need AL FLUIDS CHANGED using ONLY GERMAN made fluid from ROWE or PENTOSIN! MOBIL ONE 0W-40 is ONE OKAY oil to use but I LOVE total energy oil and PENNZOIL ULTRA EURO gives a 500,000 mile WARRANTY that is UNREAL! If you BUY IT prepare for a total SLUDGE REMOVING treatment! ANY BMW is VERY SAFE even in ACCIDENTS and they have the BEST BOSCH ABS systems there is! They are COMFY< efficient and VERy safe and last for THIRTY YEARS or more! They are a GREAT investment and unlike most american cars that size can last EASILY to 500,0000 miles with NO RUSTING! They use the BEST ATE GIRLING brakes! BUT>>> all the fluids MUST be changed at 100,000 mile intervals! BMW do EXCELLENT in crash tests, but a NEW DRIVER may be better off in a USED RUSTY TAURUS CAR that is SAFE but NOT as sporty! They get 30 MPG all day long! I LIKE the 3 series CONVERTIBLES from the 80's and they are EASY to restore to LEARN about cars and their workings! They are VERY RELIABLE! NEVER use a CHEAP AUTO ZONE battery in them as it can blow up the cols! USE A GENUINE GERMAN battery or JAP battery if needed! POWER WASH the engine to keep AIR flowing over it! At 100,000 miles REPLACE the COOLING FAN SWITCH! If you see PRESTONE GREEN IN THERE< it is the WRONG stuff! BWM coolant is BLUE or PINK! IF you remove the OIL FILL CAP and see SLUDGY brown GOO< suspect the CRANK VENT system and have it CLEANED UP or REPLACED there is a FILTER there that wil WEAR OUT! There is a TRANS KIT from BLAUPARTS or 1-800-ALL-EURO that will have the RIGHT fluids and filter for the ZF tranny! ANYWAYS i have worked on DOZENS of BMW cars, and they are ALL worth buying! They have NOT bad models at all! And WILL LAST as long as you take care of them! They have NO COMPROMISE quality control! Get a FULL SUSPENSION chck as BUSHINGS on older ones MAY be worn out! They are about $35 per set per side! ANYWYAS they are QUITE CHEAP and SAFE to own and VERy reeliable! GOOD LUCK!
