Depends on the type of 4runner you want. All 4runners are excellent and are always my preferred over a dodge truck.
But the 1st gen (84-89) with the 4cyl is a 100ish HP vehicle, that rocks hardcore with its square straight body, especially with its removable hard top on the back, that you can put a soft top on, & has a tailgate. In my opinion, looks absolutely sick.
The 2nd gen (90-95), my truck, doesnt have a removable top, but has a v6 (150HPish) and the tailgate. I love it, as even stock, i have a 5spd 4x4 that woops Jeeps in anything I've gone through with them.
Those are 2 pics of my truck. It moves a little slow, but it and the 1st gen are relatively easy to work on.
The 3rd gen (96-02) is a little more rounded body, has a liftgate, & is a little more roomy. Also has the 3.4l v6 (190HPish) that moves faster. The turbo version also kicks.
These are the 3 you can afford. Personally I'm a 1st & 2nd gen body style fan, but a fan of the 3rd gen motor.
Ask the gents here, they are all extremely helpful.
