18: 1973 Cadillac Eldorado
The 1973 Cadillac Eldorado is more reliable than you’d expect. The ninth-generation Eldorados were exceptionally clean in terms of design and features. The 500 cu in (8.2 L) V8 (1971-76) was notable for being a powerhouse. The engine set a sales record for the brand in 1971 and that also makes finding parts for these cars easy. Inexpensive repairs and a large engine bay make the 1973 Cadillac Eldorado a breeze for maintenance.

The great thing about the Eldorado besides the large body size is the fact that the powerful motor can be upgraded tremendously. These cars are notorious for performance and smooth riding experience, living up to the original Cadillac standard. This is why the Eldorado is a symbol of American quality.
