I agree, cars can be a shocking investment, but investments don't always have to increase in value to be a good investment. A good investment may pay you a good income and/or possibly give a tax deduction, just depending upon what the investment is for. Telstra shares is an example, not a lot of Capital growth but a good return in terms of dividends. During and after the GFC, bank shares were an awesome investment. Even after the bottom of the prices the dividend returns were over 10% plus franking credits in some cases, and these were blue chips like Westpac. Just depends what you are investing for. Same as salary sacrificing a vehicle, rarely a good capital return unless you pick (and sometimes compromise on) the right vehicle, but in term of tax breaks and affordability can be a great investment. Plus if you setup the residual/baloon right and then sell the car at a premium over that residual then the difference is tax free.
Just for interest sake, I looked at Westpac as I have some of them. $1.80 per share dividend, fully franked for last financial year. I bought them at just over $15 during the GFC but they were hovering around that for a year or so afterwards. That is about a 12%pa return plus I get the franking credits to offset against income tax. The shares are currently about $31-$32 so they have doubled since I bought them like 4-5 years ago but that isn't that good of a capital return if capital is what you are after.
