My heart goes out to ya bud
Mistakes are one thing, but that is just bad business on the part of Momentum Mini. My advice is to forget those losers and purchase elsewhere. I also think it would be prudent to write to MINIusa corporate, spare no detail.
I have heard that mini dealers do not like to sell cars to folks who will be taking them out of state, but a deal is a deal and and the 3-card monty b.s. after the deal was struck is mighty darned nasty!!
Mini Center in San Antonio does square business. I know several Houston folk who have made the trip to S.A. to make their purchase. They may also not want to sell a Mini that would be taken out of state, but I am sure if that is the case they would tell you up front rather than take your deposit and then change their minds.
Get in touch with corporate. Ask their advice, perhaps they can do something magnanomous in your particular case as an act of good faith.
