I do not understand the weak opinions of this fine car. The 84 Spur that I have has been a pleasure.
A good hint is to keep a very large, fresh expensive battery in the car. The fuel injection is electronic and requires power after cranking to run properly. The engines are so well designed, that they will start easily on diminished power, yet not idle well if the battery is then weak from cranking the starter. So get one that costs a hundred US dollars, and is as big as will fit in the place in the well in the floor of the trunk.
If you suspect the converter to be clogged, replace it. The O2 sensor needs to work as well. The gas and air filter must be clean.
Only use premium fuel and stabilizer if the car sits for months. Do not let it sit up for long periods. Get it to operating temperature bi-monthly at least, and drive it around the block if you don't want to go enjoy it. Lanolin that leather, and do not let it sit for days in the sun. Solar radiation ruins everything, including a Rolls.
A lot of the components are GM, so it's not like you're buying all Ferrari parts. First you have to be a car lover, then you can understand why. They are works of art.
Would you buy another car from this manufacturer? Don't Know
