1. KEYLESS ENTRY
Current Wisdom: Who doesn't love keyfob door openers? But magnetic entry cards-such as those from Mercedes, BMW, and Cadillac-that open and start the car require getting used to
Outlook: Keys will be obsolete someday-it's a given
Price: $250 (keyfob)
Should You Buy It? Yes. Keyless entry will be a big plus when you sell
2. INTEGRATED HANDS-FREE PHONE
Current Wisdom: Perfect for the traveling salesman and no one else
Outlook: Driver distraction is a real issue, with legal momentum. In the not-too-distant future, hands-free may be your only choice for making calls on the road
Price: $600 and up
Should You Buy It? Time will tell. If your car is prewired for a phone, your bases are covered. Otherwise, it's worth considering
3. IN-CAR VIDEO ENTERTAINMENT
Current Wisdom: An overpriced but incomparable way to keep the kids quiet during long trips
Outlook: It'll no doubt remain popular with the sport-utility, station wagon, and minivan set
Price: $1,300 to $3,000
Should You Buy It? Even bet. It probably won't be a deal-maker (or breaker) when you sell your vehicle
4. HEAD AND SIDE AIRBAGS
Current Wisdom: The more airbags you have, the better
Outlook: Pretty much the same. In addition to front airbags, head and side ones should become ubiquitous in the next few years
Price: $300 to $500
Should You Buy It? Absolutely. Don't even think twice
5. IN-CAR NAVIGATION SYSTEMS
Current Wisdom: You either love them or hate them
Outlook: More complete systems that include concierge and news services should eventually supplant navigation
Price: $1,500 to $2,500
Should You Buy It? Only if you want it. Little value will be left when you sell
6. STABILITY CONTROL
Current Wisdom: Useful but pricey. Usually available only on high-end models
Outlook: As with antilock brakes (ABS) and traction control, the technology will quickly expand to less expensive models
Price: $550 to $1,100
Should You Buy It? If you can afford it. That said, insist that your car have ABS
