Ask any BMW fan and he'll tell you that the E24 6-Series coupes were special. BMW tried to re-create the magic with the 8-Series a few years later, nd perhaps even with the Z8 and cars like the current 6-Series, ut somehow they can't quite capture the E24's balanced performance. So when you have a chance to own a clean 635csi like this 1979 example, ou will never regret making the purchase.To some, t's the most elegant BMW ever created, he perfect combination of sport and luxury, seamless integration that starts with the almost ideal proportions. It's not built like a sports car, ut it is long, ow, nd sleek with lots of glass area and that traditional "kink" in the C-pillar that has defined BMWs for decades. The silver paint is probably original, nd though it shows some signs of age, t also shows you how good BMW's quality was, ven in the late 1970s. Experts will note this is a Euro-spec car, ith slender bumpers, deeper front spoiler, nd a subtle black spoiler on the trunk lid, ll of which only enhance the already clean look. The chrome is excellent, he rubber components don't look like they're 35 years old, nd even the weather-stripping is supple and seals up nicely. You also get clear lenses, ncluding the distinctive taillights, nd even the chin spoiler hasn't been beaten up by steep driveways and parking lot curbs. Someone has truly loved this car.Black upholstery works rather well with the silver paint, nd you'll note that BMW used cloth inserts on their bucket seats, loth that helps hold you in place during spirited driving. It's got some wear to it, ut it's also the kind of wear that you can show off as a badge of honor. The rest of the interior is quite good, ith nice carpets and great soft parts, ncluding the dash pad. Full instrumentation is, f course, art of the BMW package, s is the fat leather-wrapped steering wheel. And if you love driving, his is a great choice because it has an Alpina-spec 5-speed manual gearbox that's just about the best-shifting transmission we've ever experienced. It does have a few options, ut you have to remember that even high-end cars in 1979 didn't necessarily come loaded up, o there are power windows and cruise control, lus an AM/FM/cassette stereo, o it's still easy to drive. You also get a nicely appointed trunk with a spare and jack assembly neatly stowed underneath.BMW's 3.5 liter inline-six really needs no introduction. A mainstay of their larger cars for nearly two decades, t's turbine smooth and torquey enough to make it feel like a muscle car around town. As a German-spec car, t has oversized valves and no bulky emissions control hardware, o it sings itself to redline and purrs along at any speed with the most joyous soundtrack from the center-mounted exhaust system. The engine bay is a little scruffy but it runs beautifully and the transmission, hich was rebuilt when the car was about 10 years old, till shifts beautifully. A limited slip differential plants the power very effectively and the all-independent suspension is athletic without being too firm for daily driving. And, s a BMW, he brakes are powerful. Those lovely BBS wheels were also part of the special edition package and wear 225/50/16 Goodyear radials, hich were quite substantial for the time.A rare find in this condition, t's only a matter of time before these BMWs become A-list collectables. Remember when the 2002 was a $5000 throw-away? This 635CSI is next. Call today!
