Do clothing, jetpacks and vehicle upgrades help you in Jetpack Joyride?

Do clothing, jetpacks and vehicle upgrades help you in Jetpack Joyride or are they purely for aesthetics?

Solution 1:

Out of clothing, jetpacks, and vehicle upgrades only the following provide any actual tangible benefit:

• Hog Magnet
• Stomper Magnet
• Teleporter Magnet
• Bird Magnet
• Gravity Suit Magnet
• Mr. Cuddles Magnet (added in the Oct./Nov. 2011 update)

The benefit of any of the Magnet items is that they attract coins that are close by without having to touch them. The clothing and jetpack upgrades provide only an aesthetic benefits, although some of them do help toward gaining certain Achievements.

Solution 2:

The Golden Piggy Pack jetpack is powered by firing $1000 bills. I noticed that unlike other jetpacks, scientists will run toward the bills making it easier to high five.
