V8 engines have come such a long way that there is an abundance of reliable and economical vehicles with V8 hearts for sale. Not only do V8 engines offer great reliability and power, but most American-built V8 engines are cheap to service, and performance upgrades are widely available, particularly for pony cars like the Mustang GT. There are also a few performance SUVs with V8s, including the Dodge Durango SRT and BMW X6 M.
