Just a litle OT here for a sec, if I may?
How quick are Millenias? I was looking to possibly sell my 89 BMW 735i and get another semi-luxury cruiser. So far I've looked at the last generation Mazda 929 which I've always loved the look of, a first generation Infiniti Q45, a Lexus LS400, and the Millenia.
Anyway, nice car, love the style. Just keep the car maintained for now and I'm sure you're modeling budget will soon increase again.
