Some things are problematic on the 1990 Renault 5 TL Campus. The brake fluid reservoir is located deep in the engine bay, making it tough to regularly check the fluid level. You will have to completely remove the rear housing for access to the tail light bulbs. To access the spare tire you will have to lower it from under the vehicle first, which can be difficult if the lowering mechanism grows rusted to the vehicle.
