Would you buy a 2003 Infiniti G35 with 56k miles

Depending on the price, yes.

56,000 miles isnt bad.i have owned a G and they are an awesome all around car!

l have an 05 G.

They really fixed up the interior a lot in the 05 year; see if u can find one of those in ur price range.

The milage is pretty decent & sounds about right.

Be prepared though for the gas econ..19 mpg combined is not very impressive, but its liveable.

Overall, they r great cars. You wont go wrong with a G, but be careful about higher milage ones. l was talking to my service rep & he was telling me about the problems to expect from an infiniti around 100k miles. Consider replacing ur car around then if u end up with one.

My next car, however, will be a Lexus. l had one before, & l realized how much l miss having one after l sold it. So keep an eye out for a Lexus u might like as well.

Goodluck.
