well... I meant reliable excluding the engine of course, that's why i mentioned i got 100 miles to the quart of oil, eventually the engine crapped out but I got about 40k out of the darn thing so for 400 bucks that wasn't bad. Too bad GM didn't understand basic metallurgy , how that got past the engineers is absolutely nuts...well that and no drain holes in the panels resulting in the rusty fenders....Reliable??? I worked at a g Chevy dealership back then. We kept a separate routing sheet for the Vega. Every one of them experienced engine failure due to silicone impregnated cylinders failing due to antifreeze leaks. We had a limit of 26 Vegas waiting for engine repair at a time. The engine had a die-cast aluminum engine block with a cast-iron cylinder head. Iron and aluminum expand and contract at different rates. The head gaskets failed due to the different expansion rates. In 1975, Chevy installed cast iron cylinder sleeves in the aluminum block and sold the Vega with a then unheard of 50,000 mile engine warranty. The engine update couldn't save the Vega probably due to its rust-bucket reputation.
