I purchased a 1973 Scout II for myself this past summer and it has been a great adventure so far. A couple of things to consider:
1) Initial cost of car Versus level of interest in restoring this vehicle.
If you are willing to get your hands dirty and have the space to work, you can easily do most of the prep work and restoration yourself. If you want to just spend the money for a fully restored Scout, then this might not be the car for you. I like tinkering around and fixing stuff, so this is a great project vehicle for me.
2) Amount of time/money you are willing to spend.
This speaks to issue #1, if you want to save $$, buy the parts online and do it yourself.
3) Vehicle Use: Daily driver, weekend cruiser or offroad classic?
My Scout is my surf wagon: the top is removed, it has only a 2" lift with custom seats and 28" tires. Not a monster truck but definitely turns heads.
4) Scout the owners first. Vehicle history, use and visual inspection to verify what you've been told.
I purchase one for very cheap ($2500), but I could see major potential in this vehicle: straight 6 engine that ran/started well, no exterior rust/pitting on the door panels, limited amount of 'thrown' grease/oil on the undercarriage, etc. This was a garage stored vehicle in Southern Cal that was used on the weekends only. All of these suggested that this vehilce has good bones and could easily be restored.
My goals are to do a frame-off restoration this winter (powder coated frame, Rust Bullet primer and Black shell sealant on the undercarriage and rear compartment, new rust-proofing/primer and paint for the exertior.
Of all the possible older 4WD vehicles (Type II Land Rover, Broncos, Scouts), I feel this one is the easiest to work on and the most affordable.
I hope I answered your questions, feel free to ask me about anything I didn't cover.
I am in the process of looking for Scout to buy for my 40th b-day gift to myself. I don't want to re-invent the wheel so I was hoping you could help me. If you have any input (good or bad) about buying, restoring, driving Scouts please chime in. Are any models better than others? What are some common problems with Scouts? etc. etc. Thank you in advance.
