if you are mechanically minded - probably OK.

but I've had 4 different Sierra cossies and did as much mileage to garage and back in all four as I did using it as a day to day car.
they are old and old technology.

I'm no dumbass ignoramous about mechanics but if you want them to run right and reliable they need checking and setting up regularly etc. this is a professional job, needing the correct equipment.

not slagging cossies - I love them - but with 20+ year old cars what can you expect, parts are going to fail.
