This is what i did

from tkinter import *
import random
import time
root = Tk()

class e():
    def startofgame():
        e.Name=str(name_entry1.get())
        e.carname=str(name_entry2.get())
        b3.grid_remove()
        b1.grid()
        b2.grid()
        tex.grid()
        name_text1.grid_remove()
        name_text2.grid_remove()
        name_text3.grid_remove()
        name_entry1.grid_remove()
        name_entry2.grid_remove()
        root.geometry( '840x275' )
        
    def card():
        e.Name="Example Example"
        e.carname="example"
        e.carseats=2
        e.fuel=80
        e.speed=40
    def customercard():
        e.cName="Example Example"
        e.people=2
        e.m=0


    def order():
        b1.grid_remove()
        b2.grid_remove()
        b4.grid()
        b5.grid()
        e.people=random.randint(0,4)
        e.m=random.randint(0,10)
        if e.people>e.carseats:
            n=n+2
        elif e.people<e.carseats:
            n=n-2
        e.cName=random.randint(0,5)
        if Name==1:
            e.cName="Vanessa Roberts"
        if name==2:
            e.cName="Frank John"
        if name==3:
            e.cName="Mark Holler"
        if name==4:
            e.cName="Arnold Waller"
        if name==5:
            e.cName="Vanessa Roberts"
        if name==6:
            e.cName="Vanessa Roberts"
        if name==7:
            e.cName="Vanessa Roberts"
        if name==8:
            e.cName="Vanessa Roberts"
        if name==9:
            e.cName="Vanessa Roberts"
        if name==10:
            e.cName="Logan paul"
        tex.insert(END,"Amount of People: "+str(e.people)+"\n Minutes: "+str(e.m)+"\n Name: "+str(e.cName)+"/n")

    def takeorder():
        b4.grid_remove()
        b5.grid_remove()
        tex.insert(END,"Driving to destination")
        time.sleep(e.m)
        b1.grid
        b2.grid
        tex.insert(END,"Mision complete")
     

    
b1 = Button(root,text="order", command=e.order ,width=10,height=2)
b2 = Button(root,text="Shop",width=10,height=2)
b3 = Button(root,text="Start", command=e.startofgame ,width=10,height=2)
b4 = Button(root,text="Take order", command=e.order ,width=10,height=2)
b5 = Button(root,text="Change order", command=e.order ,width=10,height=2)
name_text1 = Label(text="Name")
name_text2 = Label(text="Car name")
name_text3 = Label(text="Enter your name \n and your car's name \n (can be made up)")
name_entry1 = Entry()
name_entry2 = Entry()
tex=Text(root,font="14",wrap=WORD,width=50,height=15)


b1.grid(row=0,column=2)
b2.grid(row=5,column=2)
b3.grid(row=4,column=3)
b4.grid(row=2,column=2)
b5.grid(row=4,column=1)
name_text1.grid(row=1, column=2)
name_text2.grid(row=2, column=2)
name_text3.grid(row=0, column=3)
name_entry1.grid(row=1,column=3)
name_entry2.grid(row=2,column=3)
tex.grid(row=0,column=1,rowspan=6)
b1.grid_remove()
b2.grid_remove()
tex.grid_remove()
root.geometry( '240x135' )
b4.grid_remove()
b5.grid_remove()

And this is what I get

Error:
Exception in Tkinter callback
Traceback (most recent call last):
  File "C:\Python34\lib\idlelib\run.py", line 121, in main
    seq, request = rpc.request_queue.get(block=True, timeout=0.05)
  File "C:\Python34\lib\queue.py", line 175, in get
    raise Empty
queue.Empty

During handling of the above exception, another exception occurred:

Traceback (most recent call last):

    return self.func(*args)

    if e.people>e.carseats:
AttributeError: type object 'e' has no attribute 'carseats'

Can anyone help?

Where are you calling card()?
You have to call it to instantiate the carseats attribute.

Why are you using e. and not self. inside your class?

I also suggest that you use the __init__(self) to instantiate all the attributes
