1994 Chevrolet Cavalier 2.2L, 5-sp., 2-door (bought for $400 with 77k on it, I got t-boned on black ice in Feb '11 with 238k, ORIGINAL CLUTCH!!!) BEST CAR I HAVE EVER OWNED, most reliable and cheapest maintenance!
1988 Oldsmobile Cutlass Ciera, 2.8L Multiport with 45 psi oil pressure at hot idle, had on road for 5 months until a drunk driver creamed my front driver fender between 80-100 mph while he was running from the cops, got this car for free and put $1200 into it before the crash

Mom'* cars:
1973? Plymouth Duster, slant 6, former Hertz car, sold due to frame rot
1978 Oldsmobile Omega Brougham, 305 V8, relegated to spare car until the tranny went with over 300k on it
1987 Pontiac 6000 */E (oh my gawd what a piece of junk it was...) Two 2.8L Muiltiport engines with 0-5 psi oil pressure at idle, TCC solenoid went at 238k, an accident with a tanker truck that tweaked the frame when it was 2 years old, burned through endless O2 sensors, MAF sensors, TPS sensors, CPS sensors... After the accident it became a MONEY PIT, but it was comfy and when she ran right, she was a great car, complete with optional gauge package
1997 Chevrolet Cavalier LS, 2.2L electronic 4-sp auto, car was incredible in the snow, currently sitting with a bad engine, about ten feet behind where I sit (the garage is my man cave), bought with 65k, currently has 121,500 on the chassis
1999 Oldsmobile Intrigue GX (was my car)

Mom'* boyfriend (as far as he remembers):

1985 Chevrolet C-20 2wd 8-ft. single cab, 350 V8, 4:10 rear end, 3-sp auto
1995 Pontiac Grand Prix LE 3100 SFI, crashed with 238k on original motor and tranny
1975 Oldsmobile Cutlass Supreme, survived catching itself on fire, and numerous drives between CT and Oregon, burned a valve, then the frame rotted out
19xx Mistubishi Precis, total junkbox, had to wrap a bungee around the brake pedal to pull the pedal up after stopping so that you could drive again
19xx Ford Courier - he still has the tires and seats in his storage unit

Yeah, for the most part, we're a GM family.

An interesting point about the Duster...

The oil dipstick was broken, so it did not reach the pan. My mother knew to add oil to the car when the engine started knocking. She would literally hear the engine knock, pull over, add a quart of oil, and get back behind the wheel and drive. Knowing the slant-6 is a bulletproof motor, I'm not surprised.

Good question... Hmmm, let'* see I've been driving since 81'(legally)... 74' Chevy 1/2 ton with 350 & 3 speed tranny (drove till floor boards rotted out), put engine and tranny in 72' nova(would like to build another), 77' Gran Torino ( Starsky & Hutch mobile), 87' Thunderbird turbo, 85' Grand Marquis, 94' Grand Am, 99'Jeep Cherokee 4x4, 01' Jeep Cherokee 4x4(still driving), 01' GMC 4x4(still driving), and a handful of motorcycles. Pretty much in that order.
