My M45X boasts luxury and reliability while being safe and speedy!
The best luxury vehicle with a powerful V8 engine I've owned. There are all sorts of available features like lane departure technology for safety. I absolutely love the AWD, especially for snowy winters. The interior is plush leather with beautiful wood. The ride is speedy, with quick acceleration but ever so smooth. My vehicle also has added features for enjoyment like the TV/DVD player, seat warmers/coolers, back window sunshade, etc. I have had no mechanical issues nor fixes since owning this car. The only thing I noticed is I do have to add extra oil every now and again, but the car is over 10 years old with a V8 engine. I would buy this car again.

My vehicle has leather seats, a sunroof.
I love my car, it's great. Beautiful leather seats, and they go back. Also the front seats have rear warmers. The only true complication is that gas is extremely expensive. But that's what I should expect for this type of vehicle. Totally recommended.

Tons of trunk space and leg room. Lots of storage space, and very good on trips.
Air conditioner doesn't work and has not worked since purchasing, brakes squeal, and water comes in my window after rain. I love the built in GPS and DVD player.
