It sounds like you have three different goals, and they break down neatly into: 1) short term: car 2) medium term: house 3) long term: retirement
First: If you can afford to (and it sounds like you can), max your 401k. Your 401k is a vehicle that allows you to "borrow" money from the government and earn interest on it (by being able to postpone taxes). Personally, I invest 100% of my 401k in an S&P 500 index. I have Fidelity, so my fund is Spartan 500 Investor Class (FUSVX). Use whatever S&P 500 index is available to you, though. If you still have money left, put it into a Roth IRA. Same deal: index fund. That covers your long term goal.
Now, for the house. I'm not sure what to say here. Most of my personal savings is also in the Spartan 500. If you've got a sliding window of 5 years to buy a house, I'd recommend the same. Convert to something more stable (bonds?) when you've made some money... then hold on to it while you're waiting to buy a house. However, consider buying one right now with little money down. Prices are stabilizing and interest rates are still historically low.
Finally, short term. You're young, so you probably won't listen (and honestly, that's okay -- I'm not picking on you): don't buy a 60k car. Spend 30k on a used Audi or BMW if that's your thing. Personally, I would recommend spending 23k on a used Honda. You will be amazed (maybe) at what 23k gets you for a used Honda. Same deal as the house, though. Buy it now, with little money down. Interest rates are really low.
Good luck. Mid 20's and already talking about saving half of your pay check. You'll be fine. Just max that 401k. And please don't get a 60k car :-)
