well, I decided for a vel satis in a country which doesn't recognize a non-german car as a vehicle and that was pretty tough. let me first of all give some pros and cons so we know what we've got here.
1. unique and head turning for not many people have even heard of it. My american car enthusiast friends never even saw one before.
2.luxury, I am talking about an interior which is incomparable to more than 95% of the cars on the roads nowadays. I feel my muscles useless after driving it sometime.
3.cheap to get second hand, you can get it in pristine condition for the money of a rusty old Audi.
4. powerband is very respectable and you get all the power you need sub 2000rpm !!
5. you never ride alone, they have a whiny bitch who'd scare the shit out of you on a highway going 160kph to inform you of a number plate light gone out
6.passenger compartment is very well noise isolated for car that old.
7.power steering very light and responsive also I have very wide tires.
8.dashboard is very neat and easy to navigate through while driving.
9.the seats being engineered fantastically, seatbelts coming out through the upper sides, separate lumbar support and back adjustment makes a schmerzlos journey for older people.
now for the cons:
1.Renault, which means the electrics go haywire when you least expect them to, but I have to say mechanically they are bulletproof thanks to the VQ35DE engine.
2.having rebuilt the engine before in my backyard and alone, I have a lot to say about servicing the engine compartment and how it is almost impossible to do anything to the engine without taking it out of the car and I mean totally out and on the table to change a water pump for example which usually takes me 1 hour on my father's old corolla.
3.trunk space is a joke, forget transporting luggage of a 4 member family anywhere, the rear seats end already beyond the rear car pillars, a focus would carry more luggage than my vel satis
4.interior rubber like surface finish will show wear almost immediately if you accidentally scratch it with your finger nails.
you have to take the front bumper off to change a light bulb, takes me 30 mins in total but I don't get why you need to do that in the first place.
5.changing an oil filter on the 3.5 engine needs some special skills and you won't be able to do it yourself if you're the youtube video type person.
to sum everything up, I have to say that knowing buying a car you're investing money in a consumable product which means it's going to suck down money sooner or later. better buy a car you like so you wouldn't be cursing your life buying that 60 euros lambda sensor when they all cost the same for every car manufacturer at the end. if you have mechanical questions regarding it's engine I am pleased to answer them and I hope I add knowledge to this small community.
