celica, z, g35.
there all good cars, but think twice to sell one to get another. a pic between these cars is very confusing, cz they all look nice and you just want them all at once. remember, celica has that unique agressive look, z is 2 seater(meaning more insurance) and g35 leans more to sporty luxury. theres always a limit you cant push ur car more than that, so you cant really drive faster. and remember, is it gonna be worth the extra speed that ur celica doesnt currently have. is it worth the 10,000? if its looks, then different story. go check out some reviews, test drive them both, and good luck
