Your first car or first new car? My first several cars were used, but if you've got the resources, go for it.
I think that comes down to what sort of vehicle you want.
Do you want Accord-size sedan or an SUV?
In my situation I'll gladly accept the higher efficiency and ride comfort of a sedan at the expense of what an SUV has to offer.
It's also very possible that the RAV4 PHEV will be very expensive, once you've got it opted up to your preferences.
I for some reason like the high-riding position of the SUVs. Otherwise, nothing interests me in particular. Regarding new car/old car purchase, I had a Camry 2005 for few months for my internship and sold it off. Now that I have a full-time job, planning to buy a good car now.
While I could buy a 3-4 year old recently used Honda/Toyota for 16-18k, my interest for future transition to all-electric, ability to claim the federal tax credits and my low driving requirements are what draws me to a PHEV now.
Given that RAV4 prime might be out this summer, I will probably wait a bit for the price. If the base model is similarly priced to that of Clarity's, then I feel the RAV4 might provide more value for money. Let's see.
