'99 Ranger value

Perhaps purchasing a '99 Ranger, but want to establish the appropriate private seller price. Any help anyone can be will be greatly appreciated. Here are the basic details.
* Decent exterior and interior condition
* 4 dr. club cab, 4 x 4
* 124K miles, but new engine, dealer installed only 10K miles
* Auto transmission rebuilt 4K miles ago
* Canopy
* Drives good and seems from first blush to be OK.
I'm looking at finding the fair price AND to learn of any problems the '99 Bronco might have to be aware of.

Thanks! ~ Zmanwa
