The Wu's are living the life of a thousandaire. Driving a $90k car while renting a $100k house.
For the price of the down payment Frank put on his husband's car they could have put a down payment on a house similar to the one they are renting. I don't know about District 8 in MA but where I live they could have gotten a typical starter home, 1/4 acre 3 bedroom/1 bath house, at auction/foreclosure for the price of that car. Frank is like in his 50s and John is 40 and they would rather buy a car that John will park outside and ruin in a few months instead of buying a house and building some equity.
Just shows that Frank and his husband are both idiots with poor decision making skills and no ability to properly manage Frank's money. I wonder if John told Frank that line about the car being "an investment that will be highly sought by collector's in 20 years" or if Frank is just a tard and bought the car without needing any convincing. That car will be worth nothing in a couple months when John totals it, tries to "upgrade" it or otherwise destroys it and send it to the memory hole with the TT, the dogs and his other discarded toys.
