Forget Hybrids
Prius $21,500. msrp [dlr. Price probably higher]
Matrix $16,190. msrp [can probably be bought for less]
Extra cost of hybrid [min.]: $5,310.
Prius mpg [per owners] 42.
10,000[avg. annual mileage]/42mpg=238gal. per year
238X $4. per gal. = $952. annual fuel cost
Matrix advertised mpg 21city, 29 hwy. (21+29)/2=25mpg average
10,000[avg. annual mileage]/25mpg= 400 gal. per year
400gal. X $4. per gal. = $1,600. annual fuel cost
$1,600. - $952. = $648. annual fuel savings w/Hybrid
$5,310. {extra cost}/ $648. {annual savings}= 8.2 years to break even. By which time, with changing technology, it will be too costly to maintain & have no resale value.
Look for good deals on Suzuki, Subaru, etc. they tend to be overlooked. ALWAYS run a carfax & have the vehicle inspected by an inspection company like carchex or mechanic.
