Well next time you are going to give a car away look me up. Seriously though, with all due respect why not just go find a nice clean low milage Maxima, Camry or Accord? More common, cheaper, less to maintain, better on gas. I would go that way if as you stated, you just want something for a weekend/getaround car.
I would also stop looking at the first gen Q45's if that is what you are also considering. Talk about potential maintenance headaches. Don't take my word for it. Just go to the NICOclub.com G50 forum and peruse that for a while. The early Q's are beautiful cars but if they were not maintained by a Infinity trained technician on a regular basis stay away. Add to that the fact that IF you buy a first gen Q you had better have a Q45 mechanic lined up before hand because you are going to be on a first name basis with him soon. I would love to own a 94-96 Q but I got scared off because of the potential recurring issues with the cars.
That said any expensive luxury car is going to cost big bucks to keep in like new shape. That cost just keeps going up with the age of the car too. A 14 to 16 year old LS is going to cost you dearly in proper maintenance if you don't want to be left stranded on the side of the road. I think if you still only want a Q, LS, or BMW, for reliability purposes only I would stick to the LS. Right now on AutoTrader there are some super looking low milage first generation LS's for sale. Just MHO.
