This was my first car, which was to be followed by another "5" three years later, a TR. Both 5-doors BTW. The latter one I still own and somehow this proved/proves to be a much better car than the TL described here... Reviewed by yours truly as well.
I don't have the TL's exact records anymore, but this I remember:
* Outer sills rusted badly; were replaced shortly before I got the car at a relatively huge sum of money, but even then were "through" once again within two years.
* Engine and carb needed frequent tuning, tell-tale was a gradually declining top-speed of sometimes not more than 125 kph in fifth and random stalling - preferably at junctions...
* Frequent starting-trouble in damp conditions. In hindsight it could have been that the starter-motor was a lemon. Not quite sure.
* First gear's tendency to drop out of engagement eventually turned so bad, that driving away from a steep incline was no longer possible. I had to keep it pushed in first while moving off at all times, and was just one hand short to use the handbrake! Lucky to live in a flat country... Foreign trips were plain impossible because of this and indeed were never made by me with this car.
* Bonnet showed severe underside-rust, but then the whole car gradually acquired a brownish hue. From '90 onward, better rustproofing was used at Renault.
The TL was a lot noisier than my TR is, as its diminutive 1.1 engine struggled to keep up with traffic.
Interior trim and dashboard were almost punishingly sparse.
Steering was, strangely enough, significantly more vague than the TR's; which is better than average.
Fuel consumption was pretty bad for a 1.1 at about 1:13 (1 litre in 13 km's) as my TR will always better 1:15, on longer trips even up to 1:17,5. That's with a bigger engine (1.4)!
