Buying a tacoma

Hello,

I never thought a truck would get my interest. Been owning 2 seat sports cars all my life until I bought a jet ski .

I am looking for a 4 cyc extended cab (plain as possible). Do you negotiate asking for invoice or under? I have bought over 10 cars but never a truck.

I am in socal so the tax is 9.75% What would be a good OTD price for 4 cyc, auto, extended cab, no other options?

Does the back seat hold a kid that is 4-12 years comfortablely? I have a son who is 4 still uses the baby seat

Thanks,
Tntrac
