Funny 40th Birthday Card for Him - Check Engine Joke Design

• OFFICIAL 40,000 MILE CHECK - UP - The perfect card for the guy turning 40. It humorously compares his aging body to a classic car: valuable, stylish, but prone to random "Check Engine" lights (aka back pain and mysterious clicking noises in the knees).
• VINTAGE RUSTY METAL DESIGN - Featuring a hyper-realistic distressed metal texture and a glowing dashboard warning light. The gritty, industrial aesthetic makes it the ideal "Man Cave" style greeting card for mechanics, gearheads, and car lovers.
• HEAVY DUTY 300GSM CARDSTOCK - Printed on premium 300gsm (110lb cover) stock that feels as tough as a car manual. The matte finish ensures the "rust" and "cracked glass" details look authentic and rugged, not shiny or cheap.
• STANDARD 5X7 INCH SIZE - Measures 12x17cm (approx. 5x7 inches) folded. The interior is blank and uncoated, providing ample space to write a list of suggested "repairs" or simply wish him a Happy 40th Birthday before his warranty expires.
• INCLUDES RUSTIC KRAFT ENVELOPE - Comes paired with a durable, eco-friendly kraft envelope that perfectly matches the vintage garage theme. Packaged in a protective sleeve to ensure it arrives in mint condition (unlike his 40-year-old suspension).
