Has nothing to do with a head start nor starting a family I mean they were 16 and 17 no one is thinking about marriage and kids for buying a scion tc (2 of them) and a Lancer. Her mom just wanted to buy brand new just because and never taught them fiscal responsibility nor really utilized it herself.
1st sister-in-law crashed in a severe roll over (escaping through the sun roof) because she chose to drive on ice while wearing a boot due to a broken foot 8 months into owning the car, luckily the friend who was in the car only had scrapes. Next new car her mom got her she quit paying the monthly amount to her parents couldn't afford it (she was 2 months behind paying a reduced amount per month) then (against both my husband and I's opinions) her mom without her knowledge took that vehicle and used it and another towards getting herself an infinity (which she hardly drove and ended up selling with 2 years) leaving her daughter with nothing. I wholeheartedly have the stance that the daughter needed to pay per month, I hated how her mom set her up to fail and the underhanded removal of the car with no knowledge.
2nd sister-in-law loved the idea of getting a sweet trim kit on the tc and mom agreed. Grandmother stepped in to help pay as well. Car was hardly used and they ended upside down in the loan for various reasons. Car eventually taken back.
It even affected my husband who had a scion tc (different than the other two) and his mom pressured him to allow her to take that car and use it towards her getting a new Explorer, in turn she'd give him the Corolla they had (used old enough in age) then he could use that to get another vehicle. Totally against my judgment but ultimately not my choice. Eventually my husband got another car (new although with his own and using the Corolla) however that loan went into calculations for our mortgage as there was more than 6 months left on the loan. Had he kept the scion tc it would not have been.
The mom and step-dad treat cars like revolving doors and their kids (except my husband who still has that car he bought) do too. Never really getting ahead, one sister buys luxury cars that forever have problems, her Benz has been in the shop I swear more than she's driven it. The other sister-in-law never grasped payment schedules and has had cars that break down too much (although they aren't new though) and when she got married her husband was the same. Their join decisions with car loans (and failure to pay rent that went to collections) ended up with her having to file bankruptcy although that was after her and her husband divorced.
It was more or less the idea of having to buy new because used was unacceptable and not really having the kids understand the finances. There's no requirement the first car has to be new though certainly safety records and features should be a thought.
